redis哨兵常用命令和监控示例详解
sentinel monitor advertise 192.168.0.5 28001 2
sentinel set advertise client-reconfig-script /etc/redis/reconfig.sh
sentinel flushconfig
sentinel启动后需要手动将配置文件对应的调整为sentinel deny-scripts-reconfig no,否则不支持命令行runtime修改client-reconfig-script
# SECURITY
#
# By default SENTINEL SET will not be able to change the notification-script
# and client-reconfig-script at runtime. This avoids a trivial security issue
# where clients can set the script to anything and trigger a failover in order
# to get the program executed.
#sentinel deny-scripts-reconfig yes
role命令
查看sentinel monitor的master names名字
sentinel masters
查看所有监控master及其配置信息
sentinel master monitor_name
查看指定监控master及其配置信息
sentinel failover monitor_name
手动进行swithover切换主从，如果有多个slave会选择哪个slave做为新的master，待测试？
sentinel moniotr
添加监视的master
sentinel remove monitor_name
将监视的为name的master移除监视
sentinel set
sentinel flushconfig
将sentinel信息写入到配置文件中
sentinel配置文件示例：
daemonize yes pidfile "/home/redis/sentinel/25000/redis.pid" loglevel notice protected-mode yes bind 192.168.100.5 logfile "/home/redis/sentinel/25000/redis.log" port 25000 dir "/home/redis/sentinel/25000" # Generated by CONFIG REWRITE sentinel myid 0338c4ceb7cf39a8037a22fa17d0f7a76923b5a0 sentinel deny-scripts-reconfig no sentinel monitor advertise 192.168.100.5 28001 2 sentinel client-reconfig-script advertise /etc/redis/reconfig.sh sentinel config-epoch advertise 4 sentinel leader-epoch advertise 4 sentinel known-replica advertise 192.168.100.6 28001 sentinel known-sentinel advertise 192.168.100.7 25000 06f937e1d35496dc66d2899e3b25e286ff91d658 sentinel known-sentinel advertise 192.168.100.6 25000 ede86ac0b7d2ff7b532d0e5352ba6e33dd36670e sentinel monitor mymaster1 192.168.100.6 28002 2 sentinel client-reconfig-script mymaster1 /etc/redis/reconfig.sh sentinel config-epoch mymaster1 5 sentinel leader-epoch mymaster1 1 sentinel known-replica mymaster1 192.168.100.5 28002 sentinel known-sentinel mymaster1 192.168.100.7 25000 06f937e1d35496dc66d2899e3b25e286ff91d658 sentinel known-sentinel mymaster1 192.168.100.6 25000 ede86ac0b7d2ff7b532d0e5352ba6e33dd36670e sentinel current-epoch 5
sentinel client-reconfig-script脚本示例
#!/bin/bash
check_time=$(date +"%F-%T")
master_name="$1"
from_ip="$4"
from_port="$5"
to_ip="$6"
to_port="$7"
#填写自己正确的机器人链接

{
"msgtype": "text",
"text": {
"content": "【'$check_time' '$master_name' redis failover】\nfrom\n'$from_ip:$from_port'\nto\n'$to_ip:$to_port'",
"mentioned_list":["xiaodongl"]
